To all 'Lo/0m it 'may concern.'

Be it known that we, HARRY B. KUNT?. and Garnica T. KUNTZ, citizens of the United States, residing at Port Townsend, in the county of Jefferson and State of lashington, have invented certain new and useful` Improvements in lVrenches, of which the following is a specification.

This invention relates to wrenches, and has for its object to'construct a wrench, the jaws of which may be arranged at any desired angle to the handle thereof and retained in this position through the instrumentality of a. ratchet and pawl mechanism.

1t is further designed to provide a means whereby the movable jaw may be detached, if so desired, from the body' of the wrench, and further to provide a. means whereby said movable jaw is adjustable independent of the handle.

lith the above and other objects in view, this invention consists in the combination, construction and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein: e

Figure 1 is a side elevation of a wrench constructed in accordance with the present invention; Fig. 2 is a front elevation thereof; Fig. 3 is a similar view taken opposite to Fig. 1 of the handle structure; Fig. 4 is a side elevation thereof; Fig. 5 is a section taken along line 5-5 of Fig. 1; and Fig. 6 is an inside elevation of the stationary jaw.

Referring more particularly to the drawings, 10 indicates a handle cast of one continuous piece of material, having at its upper terminal a laterally or transversely arranged bearing 11 and a depression 12 formed inwardly of the said bearing and on each side of the projection 18 centrally formed on the handle. The depressions 12 have pivoted therein the pawls 14 which are normally forced toward the bearing 11 by the spring 15 which is mounted in the opening 16 formed transversely in the projection 13 and operate transversely against the inner terminals of the pawls 14. The stationary jaw indicated generally as A is pivotally mounted upon the bearing 11, as will hereinafter be more fully described. This stationary jaw comprises a shank 17 having a longitudinal dovetailed groove 18 formed therein. A slot 19 is arranged obliquely across the face of the shank 17 and Specification of Letters Patent.

provides a means .whereby the movable jaw may be secured to the stationary jaw and operate in the slot 18. A transverse head 2O is formed at the upper 'terminal of the shank 17 and forms one of the jaws of the wrench, while a transverse bearing 21 is similarly formed at the lower terminal of the shank 17, said bearing forming a support for the movable jaw, as will hereinafter be more fully described.

The shank 17 Ahas formed thereon a suitable ratchet. wheel 22, which, whenthe jaw is mounted upon the bearing 11 of the handle 10, operates in a circular depression 23 formed inwardly of the bearing 11. When the jaw A is in its operative position the pawls cooperate ywith the ratchet wheels 22 and retain the jaw A in a rigid and adjusted position. The terminal of the bearing 11 is provided with an interiorly threaded opening 24, in which a screw is placed for the retaining of the jaw A upon the said bearing.

The bearing 21 of the stationary jaw has swiveled therein a screw 25 which is operated by the finger piece 26 formed adjacent to the bearing 21. This screw projects into the movable jaw 27, and by the operation of said screw said movable jaw 27 is operated longitudinally as desired. A dovetailed projection 28 is formed on the rear surface of the movable jaw 27, and isadapted to reciprocate in the slot 18 of the stationary jaw 11, said projection being inserted in the groove 1S by means of the obliquely arranged slot formed therein.

In order to provide a means whereby the pawls may be restrained from movement, a slot 29 is formed in each side of the handle k10 adjacent to the depressions 12, and has slidably mounted therein a stop or finger piece 30, said stop or finger piece adapted to rest against the cooperative pawl and secure he same from movement.

From this construction it will clearly be seen that by sliding the stops 30 in the slot 29 and exerting a pressure upon the lower terminals of the pawls 14, the stationary jaw A may be swung about its pivotal point to any desired angle. It will further be understood that by the rotation of the screw 25 the position of the movable jaw 27 is regulated. If so desired, the said movable jaw can readily be removed from the stationary jaw by primarily removing the screw 25 and partially twisting" said jaw until the projection 28 coincides with the opening 19 and the groove 18.

Having thus fully described our invention, what we claim as new, and desire to secure by U. S. Letters Patent is:

l. A Wrench comprising a handle, a bearing mounted on said handle, a stationary` jaw carried by said bearing, a shank formed on said jaw, said shank having a grooveV therein and an oblique slot crossing said groove, a movable jaw slidably mounted in saidl groove and means to adjust said jaws with relationy to one another.
